Creating Beef and Garlic Butter Pasta can be effortless when you follow these simple steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta, cooking according to package instructions until al dente. Drain and reserve about 1 cup of pasta water.

2. Prep the Beef: While the pasta cooks, season the sliced beef with salt and pepper.

3. Cook the Beef: In a large skillet over medium-high heat, melt 2 tablespoons of butter. Add the beef in a single layer and cook for 2-3 minutes until browned. Flip and cook for another 1-2 minutes until cooked through. Remove beef from the skillet and set aside.

4. Make the Sauce: In the same skillet, melt the remaining 2 tablespoons of butter. Add minced garlic and sauté for about 1 minute until fragrant. Be careful not to burn the garlic.

5. Combine: Return the beef to the skillet. Stir to combine with the garlic butter. If the mixture seems dry, add reserved pasta water a bit at a time to achieve the desired consistency.

6. Add the Pasta: Toss the cooked pasta into the skillet, mixing well with the beef and sauce. Allow the pasta to absorb some of the flavors for about 1-2 minutes over low heat.

7. Season: Add red pepper flakes for a hint of heat, if desired. Taste, and adjust the seasoning by adding more salt and pepper as needed.

8. Serve: Remove from heat and transfer to serving plates. Garnish with chopped parsley and sprinkle with grated Parmesan cheese.

Each of these steps is designed to ensure that the flavors meld perfectly, giving you a delightful Beef and Garlic Butter Pasta dish.
